Q.3  - Each 3 marks

(A) Convert into improper fraction 10 3/4

Answer: (10 x 4 +3) /4 = 43/4

In proper fraction Numerator is smaller then denominator while in Improper fraction Numerator is Greater then Denominator

B) See the pattern and write the next numbers - the numbers below are multiple of 13 hence the pattern is as follows

13, 26, 39, (13 x 4 = 52), (13 x 5 = 65), (13 x 6 = 78) .....................

C) If a 15 kg fish costs Rs. 3750. What is the cost of 1 kg of that fish?

This is a question of Cross Multiplication.

15 kg ======= Rs. 3750

   | 10

---------

       3

 

13 / 5 = Quotient + Remainder/ Divisor = 2 + 3/5
